10 Claims.

This invention relates to double sash windows and particularly to amanner of mounting such windows so that they may be readily washed onboth sides from the interior of the building. Such 5 windows are shownfor instance in my Patent No. 1,687,116, dated October 9, 1928, butthese windows were of the reversible type and I found that it wassomewhat difficult and awkward to manipulate the same, especially withlarge and heavy windows.

Also, this arrangement required a certain remodeling of the windowcasing structure.

tions.

The weight of sash windows, as is well. known, is counter-balanced byweights and an-.

other object of my invention is to arrange the structure so thatt eweights be utilized to help support the windows when-they are temporarily changed to the easement type. This is of especial advantage inlarge windows in'which their weight would otherwise tend to make themsag and tear away from their connections whenswung inwardly.

Another object is to provide a structure for the purpose arranged to beeasily applied either to new construction or on windows already inplace.-

These objects I accomplish by means of such structure and relativearrangement of parts as will fully appear by a perusal of the following.

Referring now more particularly to the charactersoi reference on thedrawings, the numeral 1 denotes in general the casing for the double Thewin dows are spaced apart transversely of the casing and said casing isprovided with guide beads i between the windows partially counter-sunkin the casing and with inner beads 5 bearing flatly against the casing.lhe lower portion ia of the right hand intermediate bead, for a lengthgreater than the height of the sashes, isremovable. It is held in placeat its lower end by its usual socketed fit in the casing and at itsupper end by a swing clamp 6 pivoted on the fixed bead above, as shownin Fig. 15.

Similarly, the lower portions to of both the inner stops are removablefrom their upper portions and from the casing. They are removablysecured in place by hand screws 7 turnably mounted on plates 8 securedto the stops and projecting through the same for engagement with tappedsockets 9 driven into the casing, as shown in Fig. 14. Removal of thesestop portions enables thev windows to be moved inwardly when both sashesare lowered to the same level, as will be evident.

The cords 10 of the usual counter-weights 11 on the sash show-' i theright hand side of the sashes are provided on their free ends withenlargedheads 12. Each head has detachable engagement with a slottedsocket member 13 set in the corresponding sash frame at the bottom ofthe cord groove 14 in the edge of said frame, as shown in. Figs. 16 and17.

The outer sash 3 has horns 15 depending from its lower corners as usualthese are cut off as necessary as indicated in Fig. 11 so that the bot-10 tom of the horns is on a level with the bottom of the inner sash whenthe tops of the sashes are on a common level. hand horn a plate 16 issecurely attached, from which a pivot pin 17 dependsyas shown in Fig.11.5 11; this pin being as near the inner and left hand edges of thewindow as possible.

In the lower left hand corner of the inner sash 2 is mounted a verticalsocketli; also close to the left hand and inner edges of the sash. A pin29 19 is slidable in this socket, being connected to a clamping screw 20whose head rides in a vertical slot in the socket and which is exposedto the inner face of the sash, as shown in Figs. 12 and 13. This pin isarranged so that when in its lowest position it depends to the samelevel as the pin 1'7; and whenraised to its limit it will just clear thebottom of the sash. The clamping screw 20 or any other equivalent deviceenables the pin to be rigidly held in either position.

On the upper edge of each sash frame at the left hand corner is fasteneda plate 21 from which a pivot pin 22 projects upwardly in verticalalinenient with the corresponding lowerpin. Fig. 8 shows a permanentinstallation. If a deg j'itachable installation is desired the plates210.

having the upstanding pins 22a thereon are removable; each plate beingseated on the top of the sash and located place by side and end flanges23. The plate is reinovably secured in :3 j place by a hand screw 24mounted on a yieldable strip 25 secured to the plate; said screw beingadapted to engage a tapped socket 26 sunk in the top of the sash. Thisarrangement is shown in Figs. 9 and 10. The presence of these gr; pinswhether detachable or permanent does notinterfere with the opening orclosing of the windows in the usual way. .Their purpose-is to serve aspivots for the windows about which the latter may swing inwardly, whensaid pivots are sup- EQ- I' ported as follows:

Adapted to rest on the window sill and to straddle and detachablysecured to the adjacent vertical portion of the window casing is a Cclamp 27 having a pair of blocks 28 mounted on its up-v per surface forseparate transverse adjustment, to serve for different thickness ofsashes. The upper surface of the blocks is provided with slots 29 and 30in which the lower pins 19 and 17 respectively of inner and outer sashride. The slot 29 extends transversely of the window in an inwarddirection and is arranged so that the inner sash when swung inwardly andwith the pin at the inner end of the slot, offers no interference withthe full inward swinging movement of the Touter sash, as shown in Fig.l. The slot 30 is arranged so that the outer may be swung inwardly, whenits pivot pin is moved along the slot, without interfering with theadjacentintermediate bead 4 or w h outer weather strip '31 on thecasing.

- The inner ends of both slots are provided with short reverse bends Bto receive the pivot pins and hold them against an undesired tendency toreturn to their normal positions at the opposite ends of the slots.

'vided as an integral part of said clamp.

To the bottom of the left Adapted to be disposed above the sashes and tobe clamped against the casing is a similar 0 clamp 32 having slottedblocks 33 adjustably mounted on its under surface to receive the upperpins; the slots being of course the same length and having the sameslope as those of the lower clamp. To support this clamp in a definitehorizontal position an upstanding bar is pro- A pair of transverselyspaced circumferentially grooved pins 34 project toward the windowcasing from the bar. Said pins are adapted to enter vertical keyholeslots 35 provided'in a plate 36 secured to the casing and extendingunder the intermediate bead 4 011 both sides of the same, as shown inFig. 6. The plate slots are arranged so that their large ends areuppermost and receive the heads of the pins, the lower narrow'portionsof the slots engaging in the pin grooves, shown in Fig. 5. When the pinsare at the bottom of the slots the clamp blocks 33 are supported at theproper level to engage the upper sash pins.

In operation the removable stop portions are first withdrawn. The lowerclamp 27 is then mounted in position under the sash and said sashes arethen lowered so as to cause the bottom pins to depend into thecorresponding slots in the clamp blocks. The blocks areinitiallyadjusted if necessary so that their spacing corr sponds to thetransverse spacing of the sashes. Independently thetransverseialineinent of the clamp as a whole may be assured by the factthat the outer clamping screw 27a of the clamp is only used to make aninitial adjustment i the position of the clamp; while the inner clamping1 and engaged with the upper sash pins; any necesi sary adjustments. ofthe clamp or its blo as being of course first carried out just as wasthe case with the lower clamp. The sashes are then separately swunginwardly a short distance so as to expose the cord connecting members inthe edges of the sashes and allow the cords to be disengaged. The sashesmay then be swung the remaining distance, an inward pull being exertedat the sametirne'so as to cause the pins to travel along the slots untilthey engage the reverse bends B. The outer surfaces of the windows arethen exposed to the interior of the building and are convenientlypositioned for washing.

If the windows are large and heavy I utilize "the counter-weights to aidin supporting the weight of the windows in the following manner:

Swivelly connected to the bar 32a are the end blocks 37 of a pair ofblock and tackle units. The other end blocks are provided with hooks 38adapted to engage slotted plates 39 secured on top of the sash framesover recesses 40 out therein, as shown in Fig. '7, intermediate theright and left hand sides of the sashes. The free ends of the cables 41of the block and tackles are provided with hooks 42 adapted todetachably engage with the heads 12 of the counter-weight cords, asindicated in dotted lines in Fig. 1, when such heads are disengaged fromthe windows as previously stated. The weights thus act on the block andtacklesv to draw the blocks together and thus yieldably support thesashes in the horizontal position as swung inwardly, without tendingdirectly from their top pulleys to the sashes and which would cause asevere binding, besides being in the way.

cords To prevent possible accident the clamps are tied together by achain or flexible cord 43. The weight of the upper clamp acts as ananchor for the lower clamp while the latter is being applied and in caseit should slip out of the Window, and

vice versa.

While each sash preferably has a complete set of pivot pins of its own,one pair of clamps will serve for all the windows of the same size in asin le building and can be adjusted for all the sizes, while oneadjustment of such clamps will of course serve for all the windows ofagiven size.

From the foregoing description it will be readily seen that I haveproduced such a device as substantially fulfills the objects of theinvention as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended claims.
